"Missed miscarriage"

So I found out at my 12 wk scan that my baby was measuring 71/2 wks! I was told I needed to go up Oldham GAU to discuss my options! I opted for medical management which involved taking some tablets! This happened on Thursday all was fine went home and told to ring back on Saturday with my ' vaginal bleeding status' I have been trying since 08:45 this morning to speak to someone and every time they told me to ring back the nurse is busy! I understand that nurse is busy but I've been told to ring up. My health is just as important as those on the ward and someone should return my call! I understand these things happen but it's still an upsetting time! 5 times I've tried calling and 5 times they've fobbed me off! Feeling very frustrated, annoyed and upset!
